The present study was conducted on the large intestine of 36 post hatch guinea fowl. The birds were divided into six groups on the basis of age viz. group-I (day-1), group-II (days-7), group-III (days-15), group-IV (days 30), group-V days-120 and group-VI- (days-180). Various morphmetrical parameters of the different segment of large intestine (right and left caeca, colon and cloaca) viz. weight, length, thickness and diameter were recorded from proximal, middle and distal portion of the segment. A significant increase in the weight, length, diameter and thickness of all segment of large intestine was observed from day 1 through 7, 15, 30, 120 and 180 days of post hatch life (0.05%) except thickness of colon and cloaca increased significantly after 15 day of post hatch.
